Victoria Patricia "Vicky" Jefferies is the mother of Tyler and Sonny Jefferies.
Peter Barlow invited Vicky to Roy's Rolls in September 2018 in order to talk about her troublesome son Tyler - who had been making Simon Barlow's life misery after he had given Tyler's name to the police for the attack on pensioner Flora McArdle. Refusing to accept any wrongdoing on her son's part, Vicky speculated that Simon was actually the instigator - which infuriated Peter.
Later, Vicky was unknowingly employed at Underworld by Peter's business partner Carla Connor. Unable to fire Vicky in fear of Tyler's wrath against his son, Peter was forced to keep her on in the packing department. Working her way up to the position of a machinist, Vicky began causing trouble for her colleagues - most notably singling Sinead Tinker out for slacking which led to a brawl between the pair. Peter found himself forced to suspend both of the women for a week however, when he intended to allow Vicky back, his personal assistant Sarah Platt informed him that the other workers were threatening a boycott if she returned to work. In order to appease everyone, Peter decided to get Vicky a job at another factory - Natty Knicks.
Three months later, Vicky returned to the area after overhearing Tyler boasting to his mates about getting Amy Barlow pregnant. Originally Vicky was keen to ensure that Tyler would be involved in the child's life, but lost all bargaining powers when she found out from Amy's parents, Steve and Tracy McDonald, that Amy was underage at the time of the conception and that Tyler had committed a criminal offence by sleeping with her. In order to get rid of Vicky, Tracy pretended that Amy had already went through with an abortion - but Vicky soon discovered the truth and demanded a DNA test. However, Steve pointed out that proving Tyler's paternity would result in him receiving a prison sentence and a place on the sex offender's register.
With Vicky having seemingly dropped the matter, Steve and Tracy made plans to adopt the baby themselves - meanwhile Vicky had met with Robert Preston and arranged for Tyler to be given a dish-washing job at the Viaduct Bistro in order to prove to Amy that he was serious about supporting her and his newborn baby. Disgusted that Vicky was back on the scene, Tracy reported Tyler to the police for statutory rape - although, Amy refused to make any statement and the case against him was dropped. Tired of the pressure she had been put under, Amy went through with an abortion - which she kept secret for a short time.
Eventually, Tracy discovered the news of her daughter's abortion and fought with Vicky in the street. Bistro boss, and Amy's former stepmother, Michelle Connor took Tracy's side and forced Robert to sack Tyler. Robert was unwilling to abandon Tyler, and found him a place in a kitchen at a friend's restaurant in Macclesfield under threat of instant dismissal if he messed up. Grateful, Vicky thanked Robert and the pair remained in contact - ultimately engaging in a relationship following his break-up from Michelle.
Vicky fell pregnant with Robert's child. On the point of ending the affair, Robert changed his mind when she told him of the pregnancy; because he was desperate to father a child, rather than for love of Vicky. Robert would continue to mislead her into believing that he was not dating Michelle behind her back, despite his avoidance of a full relationship with Vicky, and particularly her desires to move to Ireland as a family. This led up to the late stages of her pregnancy where Vicky finally discovered Robert's double life. Vicky and Michelle conspired a plan to have Robert arrested, but this failed when Vicky went into labour and Michelle helped to deliver her second son, Sonny Jefferies. Vicky would not allow Robert to meet his son when he was born, and ultimately never got the chance to change her mind, as Robert was accidentally shot dead on Christmas Day and Vicky would leave for Ireland with sons Tyler and Sonny.
